“It seemed like a good idea at the time” has been the limp excuse of many a person whose actions later became cause for regret. Although we see ourselves as rational beings, we are far more likely to act according to impulse than logic. Nor is this always a bad thing, David Lewis suggests. Impulse explores all the mystifying things people do despite knowing better, from blurting out indiscretions to falling for totally incompatible romantic partners. Informed by the latest research in neuropsychology, this eye-opening account explains why snap decisions so often govern—and occasionally enrich—our lives.

Lewis investigates two kinds of thinking that occur in the brain: one slow and reflective, the other fast but prone to error. In ways we cannot control, our mental tracks switch from the first type to the second, resulting in impulsive actions. This happens in that instant when the eyes of lovers meet, when the hand reaches for a must-have product that the pocketbook can’t afford, when “I really shouldn’t” have another drink becomes “Oh why not?” In these moments, our rational awareness takes a back seat.

While we inevitably lose self-control on occasion, Lewis says, this can also be desirable, leading to experiences we cherish but would certainly miss if we were always logical. Less about the ideal reasoning we fail to use than the flawed reasoning we manage to get by with, Impulse proves there is more to a healthy mental life than being as coolly calculating as possible.

While we know a great deal about the benefits of regional integration, there is a knowledge gap when it comes to areas with weak, dysfunctional, or nonexistent regional fabric in political and economic life. Further, deliberate “un-regioning,” applied by actors external as well as internal to a region, has also gone unnoticed despite its increasingly sophisticated modern application by Russia in its peripheries.

This volume helps us understand what Anna Ohanyan calls “fractured regions” and their consequences for contemporary global security. Ohanyan introduces a theory of regional fracture to explain how and why regions come apart, consolidate dysfunctional ties within the region, and foster weak states. Russia Abroad specifically examines how Russia employs regional fracture as a strategy to keep states on its periphery in Eurasia and the Middle East weak and in Russia's orbit. It argues that the level of regional maturity in Russia’s vast vicinities is an important determinant of Russian foreign policy in the emergent multipolar world order.

Many of these fractured regions become global security threats because weak states are more likely to be hubs of transnational crime, havens for militants, or sites of protracted conflict. The regional fracture theory is offered as a fresh perspective about the post-American world and a way to broaden international relations scholarship on comparative regionalism.
